NASAL SHIELD.

SPECIFICATION forming part of Letters Patent No. 758,030, dated April 19, 1904.

Application filed June 30, 1903. Serial No. 163,792. (No model.)

To all whom, it may concern:

Be it known that I, TnouAs GARENOE, a citizen of the United States of .America, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Nasal Shields; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in nasal shields of the class set forth in my previous patent, No. 701,538, dated June 3, 1902.

The objects of my present invention, generally speaking, are the same as set forth in the said previous patentthat is to say, the cure of the disease or complaint known as hay-fever. being an affection of the mucous membrane of the nostrils, supposed to be caused by the dust or minute particles of decayed vegetation which are brought into c0ntact with the lining membrane of the nose during certain seasons of the year.

The special or primary object of an invention of this class is to strain out the dust from the atmosphere before the latter enters the nostrils. This function removes the cause of the disease, and the patient by the continued use of the shield becomes cured.

The device consists of two members, one

for each nostril, and each of these members,

in addition to its equipment with a gauze diaphragm, is provided with a removable absorbent pad which may be saturated with a medicine adapted to heal the diseased membrane and facilitate the cure of the disease. The specific mechanism of my present invention is considerably different from that shown in my said patent. One of these features of difference consists of the adjustability of the bridge-piece connecting the members, whereby this piece may be made longer or shorter, as may be desired, thus adjusting it to the requirements of different individuals. Another novel feature consists of apivoted looking device whereby the parts when assembled are retained in position. The absorbent pad is applied to a short tube having a gauze diaphragm at one extremity, and the pad is held in place by two opposing plates, one of which is made fast to the tube, while the other is made fast to an arm connected with the bridge. This last-named plate is apertured to receive the tube and carries the pivoted locking device. 1

Having explained the objects of a device of this class and outlined the novel features of my present construction, I will proceed to describe the same in detail, reference being made to the accompanying drawings, in which is illustrated an embodiment thereof.

In the drawings, Figure 1 is a front View of the shield greatly enlarged beyond the normal size to facilitate clearness of illustration. Fig. 2 is a section taken on the line 2 2, Fig. 1. Fig. 3 is a section taken on the line 3 3, Fig. 2, viewed in the direction of the arrow. Fig. i is a perspective view in detail, illustrating the'ring or apertured frame-plate of one member, the locking device being shown in place thereon. Fig. 5 is aperspective view in detail of the short tube and the plate or flange carried thereby. Fig. 6 is a detailview of the absorbent pad. 7

The same reference characters indicate the same parts in all the views.

Let the numeral 5 designate a small plate provided with an opening 6 and having a short forwardly-projecting arm 7, terminating at its outer extremity in a clasp 8, adapted to engage an arm 9 of the bridge 10, which is also provided with aclasp 12, engaging the arm 7. These clasps are formed by making the parts with T-shaped extremities and then bending them around the adjacent parts in opposite directions. The clasps are so adjusted that while the parts are allowed relative movement they will retain themselves automatically in position when properly set or adjusted. The two members of the device are exact duplicates. Hence each member has parts 5, 7, and 8, and the bridge has two arms 9, with which two arms 7 of the two members are connected.

Pivoted on each plate 5, as shown at 13, is a semicircular device 14:, provided with two a small ear 16, the latter being employed as a finger-piece to facilitate the manipulation of the locking device.

Each member of the shield is provided with a plate 17,having a central opening surrounded by a short tube 18, havinga gauze diaphragm 19 at its inner or rear extremity. This diaphragm is omitted in Fig. 5 to permit the showing of other features with greater clearness. The tube 18 is provided with two slots 20, located on opposide sides.

Assuming that the arms 7 are connected with the arms 9 of the bridge-piece in the manner heretofore explained, the manner of assembling the remaining parts is as follows: An absorbent pad (designated 21 and having an opening 22) is applied to each tube 18 and pressed against the plate 17, the pad occupying a position between the slots 20 and the plates 17. The tube 18 is then passed from the rear through the opening 6 in the plate 5, the locking device 14 being first swung outwardly or to the position shown by dotted lines in Fig. 3. When this is done, the slots 20 will project slightly beyond orforward of the plate 5. The locking device 14 is then thrown to the locking position or that shown by full lines in Fig. 4, whereby the lugs 14 are made to engage the slots 20 of the tube 18, thus locking the parts securely in place.

When'the parts are assembled, the pads 21 project considerably beyond the metal parts, whereby the latter are prevented from coming in contact with the nasal membrane. These pads, as heretofore explained,may be saturated with any suitable medicine or substance, and they may be removed and new pads substituted by simply unlocking and removing the tube 18 and its plate 17. The old pad may then be detached and a new one substituted, after which the parts may be reassembled in the manner heretofore explained.

Having thus described my invention, what I claim is 1. In a nasal shield, the combination of two open-ended tubes, each provided with a diaphragm adapted to strain out the dust of the atmosphere, each of said tubes being also provided with an extcriorly-projecting plate, a bridge connecting the tubes, an absorbent pad surrounding each. tube and in contact with its plate, a second plate surrounding each tube, in contact with the pad and opposed to the first-named plate, and a locking device mounted on the second plate and engaging the tube for holding the parts in the assembled position.

2. In a device of the class described, the combination of two tubular parts each provided with a diaphragm open to the filteringpassage of air, a bridge-piece connecting said parts, two opposing plates surrounding each tube, absorbent material held between the plates and protruding therefrom, and a locking device pivotally mounted on one of the plates and adapted to engage the tube whereby the parts are held in the assembled position.

3. In a device of the class described, the combination of two open-ended tubular parts, a bridge connecting said parts, two opposing plates mounted on each tubular part, absorbent pads held by the plates, and a pivoted device mounted on one of the plates and adapted to engage the tubular part whereby the elements are locked in the assembled position.

4. The combination of twotubular parts, a bridge. connecting said parts, said bridge being slidable for purposes of adjustment, absorbent pads mounted on the tubular parts, means for holding .the pads in place, and a gauze diaphragm applied to each part for the purpose set forth.

5. The combination of two tubular parts, a plate surrounding each of said parts, a pad engaging each plate, another plate surrounding the tubular part on the opposite side of the pad, and a pivoted device mounted on one of the plates and adapted to engage the tube for locking the elements in the assembled position.

6. The combination of two slotted tubular parts, a bridge connecting said parts, a plate, applied to each tubular part and made fast thereto, an absorbent pad applied to the plate around each tubular part, a second plate applied to each tubular part and engaging the pad opposite the first-named plate, and a pivoted locking device mounted on the second plate and adapted to engage a slot of the tubular part whereby the elements are locked in the assembled position.

7 In a nasal shield, the combination of two open-ended tubular parts, a bridge connecting said parts, said bridge being slidable for purposes of adjustment, an absorbent pad detachably applied to each tubular part, and a diaphragm also applied to each tubular part and arranged to strain the dust out of the atmosphere which passes through the tube.

8. The combination of two apertured plates, a bridge-piece connecting said plates, a tubular part provided with a surrounding plate, the tubular part being inserted in an opening in the apertured plate, an absorbent pad interposed between the two plates, and .means for locking the parts in the assembled position.

9. The combination of two apertured plates each having an arm made fast thereto, abridge slidably connected with the said arms, a tubular part applied to each apertured plate, and means applied to each tube for straining the dust out of the atmosphere as it passes therethrough.

10. The combination of an apertured plate, a short tube provided with a plate, the tube being inserted in an apertured plate, means applied to the tube for straining the dust out arm and a pivoted locking device, a bridge adj ustab'ly connected with the said arms, a tube having a plate made fast thereto, one of the tubes being inserted in each apertured plate and slotted to engage the locking device, an

absorbent pad placed between the two plates,

and means applied to each tube for straining out the dust as the air passes therethrough.

In testimony whereof I aflix my signature in presence of two witnesses.
